More than 800 people have signed up to take part in a ‘Thunderclap’ to mark the 10th anniversary of Sandbach man Steven Cook’s disappearance.

At noon on September 1, hundreds of messages will be displayed via Facebook, Twitter and Tumblr raising awareness of the search for Steven, who was last seen outside a bar in the resort of Malia, Crete, in 2005.

Known as a Thunderclap, the social media campaign has been organised by Steven’s family.

On the webpage about the campaign, a message reads: “This Thunderclap is dedicated to bringing Steve home, telling people about our search for Steve, his possible circumstances, and informing anybody that is going to holiday in Crete, or knows someone that may live there, how they can help to bring Steven home through sparing just a few minutes of their time while there.

“Visit our website if you want to help bring our much loved and much missed son, brother and uncle home – www.findstevencook.co.uk

“Cheshire police have updated the age progression of how Steven may look now – 10 years after he went missing.

“Please help us to share it to reach the person who knows where Steven is, or what happened to him the night he went missing. With many thanks from all of the Cook Family xx.”
